TECH TREE IS POINTLESS
Almost all of tech bonuses apply on *all* planets/ships
Why would you then bother with a custom tech tree? With 14 planets being the norm for a developed account, you can simply split your planets and have 3-4 of the same race, pump their techs on their planet to reach the maximum (which will be capped, so 3-4 planets should be enough for this maximum).
The whole idea of having separate tech trees per planet becomes pointless.
It also makes absolutely no sense that each planet develops the identical technologies multiple times. Research should be on empire level. This is like, Elon Musk makes colony on Mars, and now they need to research the wheel again because... it's a new planet and what humanity already discovered does not apply.
PRODUCTION BONUSES ARE INSANE
Every race has production bonus techs that apply on all planets. Some even for the same resources, so they will overlap. When all of these bonuses are combined, production will go to the extreme levels. 10B point accounts will become the new norm.
SHIP BONUSES ARE INSANE
Same as for production, but now for ships.
THE WHOLE UPDATE IS OP
If the concept is not given more thought and redesigned, it will mess up the balance of the whole game (even when they cap the bonuses).
THE WHOLE UPDATE IS VERY HARD TO UNDERSTAND
It will not bring more people to the game, it will do quite the contrary. Imagine a newbie being thrown into V9? They would quit after a day.
